Connect and register SIP devices and applications

The SIP devices are provisioned and registered using native SIP or SIP over secure WebSocket (WebRTC).

Once the SIP devices are registered, they are reachable and ready to initiate or receive SIP sessions, such as voice or video calling.

Initiate SIP sessions from SIP or WebRTC devices​​

Registered devices can initiate and receive SIP sessions i.e voice calls or video communication between devices.

If SIP devices are behind NAT or a Firewall, a media relay service will be dynamically added to make sure that devices stay reachable as expected.

Initiate voice calling over the PSTN network

Enable external calling by connecting a SIP-trunk to a PSTN provider to allow inbound and outbound PSTN calls.

Connect to a private SIP trunk for your internal SIP service i.e an enterprise PBX or a call center in order to integrate the SIP devices with your existing voice solution.
